A modification of the method of Shapiro for the preparation of diborane was developed which gives nearly quantitutive yields of essentially pure diborane. Experimental studies of steps in the thermal conversion of diborane to pentaborane-11 were continued. The isotope effect in the decomposition of diborane suggested that the hydrogen is eliminated in the initial rate limiting step. An analysis of the subsequent fate of the triborane-7 molecule supported the belief that tetraborane-10 is next formed. Study of the conversion of tetraborane-10 to pentaborane-11 previously suggested the importance of the tetraborane-8 molecule. Support was offered for this interpretation by study of the decomposition of tetraborane-10 in the presence of carbon monoxide. Preliminary studies of the reaction of diborane with lithium amalgam are also reported. (auth)
